Study on Flame Retardance of Polyethylene

Polyvinyl chloride itself has a chlorine atom because it has a chlorine atom, so it has its own flame retardant effect. However, when a large amount of plasticizer is added to polyvinyl chloride to make it a soft PVC, it is very flame-retardant. necessary. It should be emphasized here that, in add.....
